t oa ge 2 of 5 III. Selection Of Data Feeders A. How many dsts feeders are there (six maximum)?

1 (one)

B. Identify the selected data feeders and preside the following for each:

(1) a shon description of the categories of data points it will provide (e.g., met. rad, or plant data points, by unit) and (2) the rationale for selecting it if another system can also provide its categories of data pomts.

1) all points for both units

2) a) only place radiological data is available b) most conducive bardware for adding t>dem support C. Which data feeder is the site time determining feeder? This should be the feeder which is providing the majority of the dsts points.

See above i

B-7 NUREG-1394. Rev. !

Page 3 of 5 IV.- Data Feeder Information Note: A new Ser. tion IV must be fillei: ?ut for each feeder system selected.

General Questions --

1. Identineation of Dsta Feeder

a. What is the name in local parlance given to this data feeder (e.g Emergency Response information System)? Please give both the scronym and the words forming it.

Radiological Dose Assessment Computer System < RDACS f

b. Is this the site time determining feeder?

Yes

c. How often will this feeder transmit an update set to the ERDS (in seconds)?

-15 second update frequency

2. Hardware / Software Environment

s. Identify the manufacturer and model number of the data feeder hardware.

Diversified Technology model: .. CAT 1000

b. Identity the operating system.

l SaSta Cruz Operation (SCO) XENIX -

l

c. What method of timekeeping is implemented on th!s feeder system (Daylight Savings.

3. Data Communication Details

.i . Can this dath feeder provide asynchronous serial dsts communication IRS *32-C) with fuU modem control?

Yes

b. Will this feeder transmit in ASCD or EBCDIC?

ASCII

c. Can this ferder transmit at s serist bsud rate of 2400 bps? !f net. at what bat d rate can i; transmit?

Yes

d. Does the operating system suppon XON' s contro!?

Yes

1. Are any problems foresten with the NRC using XON/XOFF to control the trans-mission of data?

Yes - )) If an X0FF is received and the corresponding XON is lost because t,f link problems (is - data corruption), some way to re-transmit the XON is needed.

2) Data not transmitted because of extended periods of XOFF is not

-buffered and will not be re-transmitted

c. If it is not feasible to recontigure a serial pon for the ERDS linkup ti.e. change the baud rate, parity, etc.), please explain why.

Serial port is configurable l

l

f. _ Dr, e ny ports currently exist for the ERDS linkup?

No

1. If not. is it possible to add additional ports?

Yes I D-9 NUREG-1394. Rev. 3

Page 5 of 5

2. If yes, will the port be used solely by the ERDS or shared with other non-emergency time users? Give details.

Solely ERDS

4. Data Feeder Physical Environment and Management

a. Where is the data feeder located in terms of the TSC. EOF. and control room?

Feeder is located in the SPDS computer roora. This room is approximately 100 feet north of the Unit 2 control room with access from the Unit 2 turbine deck

b. Is the data feeder protected from loss of supply of electricity?

Yes

c. Is there a human operster for this data feeder?

fio . User interface devices are located in the control rooms of each unit and arc on-line and available 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> a day
